Google has just release a new tool called Google Sync, a service that syncs your Google Contacts and Calendar wirelessly to your iPhone, BlackBerry, Symbian, or Windows Mobile phone.

Google Sync uses a Microsoft Exchange server to keep all of your contact and calendar data in sync over the air. If you've added a new calendar appointment from your desktop, Google Sync will push the update to your phone. Likewise, changes you make from your phone are automatically synced to your Google account in the cloud.

We've seen similar tools from third parties before—like previously mentioned NuevaSync—but an official service from Google is obviously a safer solution. We're eagerly syncing up our phones at LH HQ right now, but if you give it a go, let's hear how it worked out for you in the comments.
